"Cicada Wings: The Secret Weapon Against Superbugs Revealed"

Researchers have used simulations to study the antibacterial properties of cicada wings, specifically focusing on the functions of nanopillars on their surface. The study found that surfaces with super-small nanopillars were effective at killing and removing bacteria, leaving no accumulated dead bacteria or debris. High-resolution molecular dynamics simulations revealed that the lipid outer shell of bacteria strongly interacts with the nanopillars, leading to membrane rupture and detachment from the pillars. Adding a thin layer of titanium oxide further enhanced the bacteria-killing properties. The findings could help develop more effective antibacterial coatings for medical devices.
